Pachmayr, 1220 S. Grand' Ave., Los Angeles, Calif. 90015 Filed Jan. 21, 1966, Ser. No. 522,167 Claims. (Cl. 42-74) ABSTRACT 0F THE DSCLOSURE This invention relates generally to improvements in firearm recoil pads comprising a rubber body adapted for attachment to a gun stock and peripherally shaped in accordance with the outline of the stock end face.

The invention is concerned with improvements in apertured or recessed configurations given recoil pads to increase their cushioning qualities, and particularly where such configurations are contained in rubber bodies bonded to one or more relatively stiffer base layers or laminations adapted for attachment to the gun stock.

My general object is to provide yfor increased cushioning deflectability of the pad body by the cooperative effects of both central and side recessing of the body interior, whereby under recoil force, resistance of the body rubber is relieved by recesses opening through the laminated base, and by overlying recesses located in the sides of the body beyond the base.

According to preformed configurations, openness transversely through the pad is separated from the base recesses by a transverse internal portion of the body rubber, and is interrupted in a central plane by essentially a divider rib formation which sep-arates both the side recesses as well as individual recesses in the central and base area all as will appear.

The result of combined central and side recessing of the body is to afford desirably greater Iuniformity in deflectability of the body rubber transversely of the pad, and correspondingly greater uniformity in distribution and cushioned assumption of recoil lforces.

The invention will be more fully understood from the following detailed description of an illustrative embodiment shown by the accompanying drawing, in which:

FIG. 1 is a view showing the recoil pad in side elevation, an end portion being broken away to reveal the internal construction;

FIG. 2 is a bottom plan view of FIG. 1; and

FIG. 3 is an enlarged cross section taken on line 3-3 of FIG. 1.

The recoil pad is shown to comprise a rubber body having an outer face 11 curved and contoured for desirably conformed engagement Iwith the shoulder of the user. The inner or opposite planar face 12 of the body is integrally bonded to at least a single base lamination or composite formed for example of a relatively hard and stiff layer 13 of rubber or other suitable material, and an intermediate thinner lamination 14 made also of rubber or similar material harder than the body rubber. The base lamination 13 is peripherally shaped in accordance with the end face of a conventional gun stock to which the pad is attachable by screws insertable through the body rubber at 16 into recesses 17 extending through the laminations 13 and 14, the screw heads, not shown, being engageable against a metallic reinforcement plate 18 apertured in alinement with the recesses and shaped as best illustrated in FIG. 2.

The laminated base has a centrally elongated open area generally indicated at 19 within which the body rubber is molded to form recesses 20 defined by transverse ribs or webs 21, a central continuous rib 22 and by the side Walls 23. Recesses 20 are closed internally of the pad by a continuous integrally molded web 24 which divides these base recesses from the overlying side recesses.

The pad body 10 is molded to contain recesses which may have any of various shapes, patterns or designs, extending inwardly from opposite sides of the pad in overlapping or overlying relation to the base recesses 20. Merely as illustrative, the side recesses are shown to have the configurations indicated at 25 and 26 and defined by the diagonal intersecting web configurations 27 as integral portions of the body rubber. As shown in FIG. 3, the recesses 26 (and also recesses 25) extend inwardly to the transverse center of the body where the respective side recesses are separated by web 28 molded in alinement with and in effect as a continuation of web 22.

The effect of recoil forces transmitted from the inner pad face 15 to the shoulder arrested surface 11 of the pad, produces compression of the pad body to degrees in keeping with the magnitude of the forces. 'I'he objective of the invention in providing for greater cushioning effect and greater uniformity in cushion distribution of the recoil forces, is achieved by the overlapping or overlying relation of the side recesses 26, 27 to the base recesses 20, in that cushioning effect by deflection of the body rubber Wit-hin recesses 20, and specifically in deflection of the continuous web 24, is supplemented and total cushioning deflection of the body rubber is given greater uniformity by the ability of the rubber to deflect within the overlying side recesses, with limited central support afforded by the web continuities 22 and 28.

I claim:

1. An elongated recoil pad havin-g a rubber body and an inner face adapted to be applied to the end of a gun stock, means forming plural recesses in an elongated central area of said face and within the rubber body, said recesses occupying less than one-half of the pad thickness at its center, and means forming also side recesses within the body rubber` along opposite sides thereof in overlying separated relation to the first mentioned recesses, whereby recoil forces transmitted to the pad are cushioned by simultaneous Ideflections of the body rubber into said central area and within the recessed sides of the body.

2. A recoil pad according to claim 1, in which said side recesses are separated from the recess in said central area by an internal transverse portion of the body rubber.

3. A recoil pad according to claim 2, in which the rubber body has a divider web extending normal to said inner face continuously centrally and longitudinally within the body and throughout the extent of said area to separate said side recesses and also recesses at opposite sides of the web in said area.

4. A recoil pad according to claim 3, in which the pad References Cited includes a lamination less exible than said rubber body UNITED STATES PATENTS portion and bonded thereto to form said inner face, said lamination being centrally open in conformance with said 1,538,990 5/1925 Hawkins 42-74 central area and said divider web extending Within and 5 1,842,528 1/1932 Knlght 42-74 throughout the open area of said lamination. 3,135,064 6/1964 PaChmaYf 42-74 5. A recoil pad according to claim 4, in which the pad 3,147,562 9/1964 Pachmyf et al, 42-74 contains a metallic reinforcement member Within the 3,263,359 8/1966 PaChmaYf 42*74 rubber between said lamination and the side recesses at the location of said internal transverse portion of the 1G body.
